Overview
The PTH12000WAS is a high-performance, non-isolated power module from Texas Instruments. This module is part of the PTH12000 series, known for its compact size and high output current capability. It uses double-sided surface mount construction and synchronous rectification technology to deliver up to 6 A of output current, making it an ideal choice for applications where space, performance, and cost are critical design constraints.
The module operates from a 12 V input voltage and provides step-down power conversion to a wide range of output voltages, adjustable from 1.2 V to 5.5 V using a single external resistor. It features pre-bias startup, on/off inhibit, and output voltage adjust capabilities, along with protection mechanisms such as under-voltage lockout and non-latching over-current protection.
